Hi Budi,
I found my build diary for the
TL-1TH
http://www.buildyourownguitar.com.au...ead.php?t=2420
It does have a thin cap, not sure what timber it is but it should have some nice grain. I stained the cap with azure lagoon and it must have been a bad batch of wudtone it looks more green than blue. I found the wiring a pain when you needed to do any mods had to remove the strings and lift the pickguard on an awkward angle.
It sounds pretty good though.
Fell free to ask any more questions Budi
